Electric side-view mirrors – general information
1. The electric side-view mirrors can be adjusted up-and-down and left-to-right by a driver’s side switch located on the left door trim panel. On models with factory-installed dual power mirrors, each mirror is also equipped with a heater grid behind the mirror glass to clear the mirror surface of fog, ice or snow. On these models, the mirror heater grid is an integral component of each mirror. If a heater grid fails, replace the mirror (see Body). The heater grid switches and the heated mirror system indicator light are integral components of the heater/air conditioning control panel on the dash. If one of these components fails, replace the heater/ air conditioning control assembly (see Cooling, heating and air conditioning systems). The heated mirror relay is located in the engine compartment fuse and relay box (Fuses – general information).
2. The mirror control switch has a LEFT-RIGHT selector switch that allows you to send voltage to the side-view mirror that you want to adjust. With the ignition switch in the ACC position, roll down the windows and operate the mirror control switch through all functions (left-right and up-down) for both the left and right side-view mirrors.
3. Listen carefully for the sound of the electric motors running in the mirrors.
4. If you can hear the motors but the mirror glass doesn’t move, the problem is probably a defective drive mechanism inside the mirror, which will necessitate replacement of the mirror.
5. If the mirrors don’t operate and no sound comes from the mirrors, check the fuse in the engine compartment fuse and relay box (Fuses – general information).
6. If the fuse is OK, remove the door panel for access to the back of the mirror control switch, without disconnecting the wires attached to it (see Body). Turn the ignition ON and check for voltage at the switch. There should be voltage at one terminal. If there’s no voltage at the switch, check for an open in the wiring between the fuse panel and the switch.
7. If there’s voltage at the switch, disconnect it. Check the switch for continuity in all its operating positions. If the switch does not have continuity, replace it.
8. Reconnect the switch. Locate the wire going from the switch to ground. Leaving the switch connected, connect a jumper wire between this wire and ground. If the mirror works normally with this wire in place, repair the faulty ground connection.
9. If the mirror still doesn’t work, remove the mirror and check the wires at the mirror for voltage. Check with the ignition key turned to ON and the mirror selector switch on the appropriate side. Operate the mirror switch in all its positions. There should be voltage at one of the switch-to-mirror wires in each switch position, except the neutral (off) position.
10. If voltage is not present in each switch position, check the wiring between the mirror and control switch for opens and shorts.
11. If there’s voltage, remove the mirror and test it off the vehicle with jumper wires. Replace the mirror if it fails this test.
